we've been told that we're in a period of "Pacific decadal oscillation,"
http://jisao.washington.edu/pdo / which I think has something to do with how the earth is tilted on its axis, and that we should expect perhaps up to 40 years of cooler weather than we've experienced in the past few decades. I also read that our cooler summer (which was pretty miserable really) and ocean temperatures helped bring the fish back off the coasts of Oregon and Washington. If we here in Alaska have to suffer through gray, rainy, cold summers to restore the balance of nature, I'm okay with it, although I was kind of liking that global warming thing while it lasted.
